Disorders of the Nervous Tissue

2.3K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Parkinson's Disease: Overview

1.3K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Seizures: Classification

1.1K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Disorders of the Skeletal Muscle

1.5K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Alzheimer's Disease: Overview

1.2K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Summary

Neurologists must recognize the diverse neurological complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Early awareness of conditions like encephalitis, headache, and stroke aids timely diagnosis and patient care during the pandemic.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Virology

Background:

  • The clinical presentation of SARS-CoV-2 infection is evolving, with neurological manifestations becoming increasingly recognized.
  • Beyond common symptoms like fever and cough, a spectrum of less common complications affects the nervous system.

Observation:

  • This study details three cases of SARS-CoV-2-associated neurological disorders: encephalitis, organic headache, and ischemic stroke.
  • The cases highlight the varied impact of the virus on neurological function.

Findings:

  • SARS-CoV-2 can directly or indirectly lead to significant neurological complications.
  • Neurological presentations associated with COVID-19 require specific diagnostic considerations.

Implications:

  • Increased awareness among neurologists is crucial for prompt identification of these disorders.
  • Recognizing SARS-CoV-2 neurological complications can prevent unnecessary investigations and reduce healthcare exposure for patients.
